Zspire has developed a sharp looking bluetooth mouse. Gizmodo calls it the mouse of the future and it certainly looks futuristic.
It performs at 800dpi but isn't recommended for any major gaming habits you may have. The Zspire has a metal base and top, with plastic buttons and battery cover. If you want your mouse customized, you can actually design your own from several options, but remember, it's not going to be easy to return after that-and for $119, that may be something to consider.
On the Zspire Blog they are addressing some of the issues being discussed in the blogosphere.
1. Shape: Well, you can interpret it in many ways - we have heard "coffin" (seems pretty popular), we have heard "stealth", we have heard "diamond", we have heard "Tron" (?????). It's unique, it's different, it is NOT for gaming. This comes more from the Bluetooth side than the mouse itself.
2. Weight: It's not as heavy as it sounds - heavier than those junky plastic pieces that everyone has on their desk, but no unmanagable - try it - really!
3. Style/Ergonomics - We actually did research on this - while it appears that may be uncomfortable, our usage has shown comfort, because your fingers are put into a nice easy position. Also, the couple of points (which are not that sharp) are actually along acupuncture points that make it feel nice. The back fits very nicely into the cleft of the bottom of your hand.
4. Coldness: Well - it is what is is. Maybe a little in the morning (probably shouldn't keep it out in the cold anyway :) ) - it's style - it's also yours. And it's art - unique.
We can see where people had the coffin idea -- maybe a futuristic coffin.
There is also a copper version of the Zspire mouse.
